Definition
NAD+ IV infusion, in plain English
IV means giving medicines or fluids through a needle or tube that goes into a vein, as MedlinePlus explains. The National Cancer Institute defines intravenous as 'into or within a vein.'
Clinics typically run NAD+ drips slowly, often over several hours, because faster infusion commonly brings flushing, chest tightness or nausea.

How it connects
How NAD+ IV infusion relates to NAD+
A small 2019 pilot study gave 750 mg of NAD+ by IV over six hours to healthy men and tracked NAD+ and its breakdown products in blood and urine (Grant et al.). No adverse events were seen during the infusion.

What NAD+ IV infusion means for NAD+ therapy
IV drips need a clinic chair and hours of time, while a subcutaneous injection takes a minute at home. The two haven't been compared head to head, and neither is FDA-approved.

Questions
NAD+ IV infusion: common questions
What is an NAD+ IV infusion?
An NAD+ IV infusion delivers NAD+ straight into a vein through a drip, usually over several hours in a clinic. It's different from the at-home nasal spray and injections NADMedics prescribes.
Is IV NAD+ better?
It reaches the bloodstream directly, but no trials show better outcomes than other routes.
Can I do NAD+ IV at home?
IV therapy needs trained staff and monitoring. NADMedics offers a nasal spray or subcutaneous injections instead.
What strengths does NADMedics prescribe?
Nasal spray: 30 mg per 0.1 mL in a 15 mL bottle. Injection: 200 mg/mL in a 5 mL vial. Your provider sets your dose.
How do I report a side effect?
Tell your provider, and you can report it to the FDA's MedWatch program. Call 911 for chest pain or trouble breathing.
Do I need a prescription for NAD+?
Yes. Compounded NAD+ requires a prescription from a licensed provider after a review of your health.
